The Eldon 2 operating system for KDF9

The Design of Operating System/2

The design of Operating S y ~ t e m / 2 ~ (OS/Pm) is a result of matching the requirements of IBM and its customers for a new operating system for various models of the Personal System/P " with the need for continuity with a very large body of established DOS applications. The design of OS12 represented a significant challenge both in meeting these requirements and in making efncient use of the...

Waltzing on a KDF9

This paper describes steps to use modern technology to describe the centuries old Labanotation for illustrating dance steps. These are animated by figures constructed from ellipsoids using NUDES and graphical editors. The resulting challenges are far from conquered.

Distributed Application Operating System Operating System Api

Middleware is a class of software technologies designed to help manage the complexity and heterogeneity inherent in distributed systems. It is defined as a layer of software above the operating system but below the application program that provides a common programming abstraction across a distributed system, as shown in Figure 1. In doing so, it provides a higher-level building block for progr...

Medos-2: a Modula-2 oriented operating system for the personal computer Lilith

The Alta Operating System

Many modern systems, including web servers, database engines, and operating system kernels, are using language-based protection mechanisms to provide the safety and integrity traditionally supplied by hardware. As these language-based systems become used in more demanding situations, they are faced with the same problems that traditional operating systems have solved—namely shared resource mana...
